Although mild traumatic brain injury (MTBI) is not as common in professional baseball as in collision sports, it does occur and frequently results in significant loss of time away from the sport. To date, no study has investigated MTBI among an entire cohort of professional baseball players. ⋯ Mild traumatic brain injury is an important problem in professional baseball players, especially for catchers. This study provides a foundation for future inquiry to reduce the incidence of MTBI in those positions at greatest risk and to provide a baseline as rules and equipment evolve.

The epidemiology of football-related concussions has been extensively examined. However, although football players experience more at-risk exposure time during practices than competitions, there is a dearth of literature examining the nature of the activities or equipment worn during practice. In particular, varying levels of equipment worn during practices may place players at varying levels of risk for concussion. ⋯ Practice concussion rates are highest during fully padded practices, preseason practices, and scrimmages, suggesting that the nature, focus, and intensity of football practices affect concussion risk. In addition, coaching staff should continue to closely monitor player safety during scrimmages. Meanwhile, future surveillance should examine whether removing scrimmages, particularly those that are not fully padded, will meaningfully reduce the incidence and rate of concussions.

Meta Analysis
No association between fibrosis on magnetic resonance imaging at return to play and hamstring reinjury risk.
Connective tissue scar (fibrosis) is a common finding on magnetic resonance imaging (MRI) after recovery from acute hamstring injuries. Fibrosis has been suggested as a predisposing factor for reinjury, but evidence from clinical studies is lacking. ⋯ Fibrosis is commonly seen on MRI at return to play after grade 1 or 2 hamstring injuries but is not associated with reinjury risk.

Successful arthroscopic repair of symptomatic superior labral tears in young athletes has been well documented. Superior labral repair in patients older than 40 years is controversial, with concerns for residual postoperative pain, stiffness, and higher rates of revision surgery. ⋯ While studies show that good outcomes can be obtained with SLAP repair in an older cohort of patients, age older than 40 years and workers' compensation status are independent risk factors for increased surgical complications. The cumulative evidence supports labral debridement or biceps tenotomy over labral repair when an associated rotator cuff injury is present.

Comparative Study
All-arthroscopic suprapectoral versus open subpectoral tenodesis of the long head of the biceps brachii.
Pathologic changes of the long head of the biceps tendon are a recognized source of shoulder pain in adults that can be treated with tenotomy or tenodesis when nonoperative measures are not effective. It is not clear whether arthroscopic or open biceps tenodesis has a clinical advantage. ⋯ Biceps tenodesis remains a reliable treatment for pathologic abnormality of the long head of the biceps. Patients undergoing an all-arthroscopic suprapectoral tenodesis in the distal aspect or distal to the bicipital groove showed similar pain relief and clinical outcomes as compared with patients undergoing open subpectoral tenodesis. Open subpectoral biceps tenodesis may carry a higher complication risk secondary to a more invasive technique.
